A. Actions by IRMM
Preparation of 3 Pu solutions with, respectively, 239Pu/240Pu activity ratios about 0.6, 1 and 1.4.
Certification of isotopic ratios by mass spectrometry.
Preparation of 1 vacuum sublimed source and 1 drop (TEG) source from each solution. Measurement of 6 reference spectra per source. Total: 36 spectra.
Distribution of spectra to participants for analysis.
B. Actions by participants
Analyse the 238Pu, 239Pu, 240Pu and send results (coded laboratories) to IRMM (2-3 months).
C. IRMM to prepare a report. Draft report within 3 months.
Laboratories will be coded.
The partners use 4 different analysis codes.
Other partners may join.
